Abstract: 1478125 Radiography EMI Ltd 29 July 1974 [18 Aug 1973] 04280/77 Divided out of 1478123 Heading H4F The subject matter of this Specification is identical with that described in Specification 1,478,123, but the claims are concerned with deriving from the signals provided by the plurality of detectors receiving the radiation along respective beams in a fan-shaped spread of radiation sets of output signals, each set relating to paths through the slice of a body exposed to the fan-shaped spread of radiation which are parallel to one another, and wherein each such derived set of signals relate to beams which are differently spaced from the beams corresponding to the signals provided by the detectors and some at least of which are notional beams. In this manner the spacings of the paths associated with each derived set of output signals (which would be unequal if related to the signals provided by the detectors) are rendered equal.

Abstract: 612,499. Wringers. MAYFAIR SHADES, Ltd., WYNBOURNE, A. H., and RAINBOW, J. C. Feb. 14, 1947, No. 4396. [Class 138(ii)] A hand-operated wringer comprises an inverted trough - shaped, one - piece, casing 5 with substantially rectangular side openings 7 giving access to the rollers 2, vertical channels 4 which are secured to the side walls of the casing in opposed relation so as to form guides for the bearings of the roller spindles 1 and adapted to leave spaces for mechanism in the ends of the casing, an inverted-channel 10 located in the lower part of the casing, and a bottom closure plate 6; the channel 10 and plate 6 are secured by bolts 12 to the casing 5 and guides 4. The bolts 12 are screwed into blocks 14 welded in the lower ends of the channel 4, and also serve to secure cross-members 15 carrying pins 16 for the mounting of the usual clamps for the machine. The side openings in the casing may be closed by flaps 18, Figs. 4 and 5, which are hinged to the casing at their lower edges; the hinge mounting consists of a spring rod 33 extending lengthwise of the flap and sprung downwardly at its centre to engage a hook 37 on the inside of the casing 5. The ends of the rod 33 pass through vertical slots 34 in the adjacent flanges of the channels 4 and are then bent upwardly at 35 and backwards at 36 so as to return through the slots 34 into holes in end stiffeners 32 on the flap. In the raised position, the upper edge of the flap bears against the inwardly-flared edge 7 of the opening, and inclined flat surfaces 38 on the lower edge of the end stiffeners 32 are pressed downwards by the spring rod 33 into engagement with inclined tongues 19 on the lower edge of the opening; in the lowered position, the flap is maintained at an outward and downward inclination by the stiffeners 32 contacting the tongues 19. In addition to the flaps 18, pivoted plates 20 are provided for guiding articles between the rollers, the lower edges of the plates 20 being pivoted at 21 to the flaps 18 and the upper edges of the plates having projecting pins 22 engaging vertical slots 23 in the adjacent flanges of the channels 4. A drip tray 26, Fig. 5, pivoted under the rollers is adapted to be tilted to one side or the other of the machine according to the direction of rotation of the rollers; an upstanding projection 28 near the end of the plate 26 is engaged by either arm of a U-shaped clip frictionally gripping the spindle 1 of the lower roller. Water drains from the tray 26 through a cut away part thereof on to the flap 18. The arm of the operating handle is of non-circular cross-section for engagement with a transverse opening in a boss on one of the roller spindles. For applying pressure to the rollers, the mechanism described in Specification 612,437 is used, being located within the channel 10 and between one end of the casing and the channels 4 at that end. Specification 603,142 also is referred to in the Provisional Specification.

Abstract: 665,562. Packaging bitumen; paper and like bags. STANSFELD, R. Feb. 17, 1950. [Feb. 21, 1949] No. 4611/49. Classes 94(i) and 94(ii). A method of packing bitumen, resin, azocerite and other materials in blocks consists in introducing bitumen in a molten state to a preformed paper sack metallized on its inner face, i.e., having metal foil sheet bonded thereto, and supported in a mould or jig; the bitumen being allowed to set to form a solid block which is then withdrawn with its metallized sack from the mould or jig. Alternatively the paper sack may have a paper liner metallized on its inner face. The sack is formed of two layers of toughened paper a, b bonded together by bitumen or other water-proofing agent and has a metallized paper liner c. The sack has a stitched, stapled or other seam d folded over at its,sides. A rectangular former block is inserted into the sack to give it a preformed flat-bottomed shape, the sack is then placed in a mould having one hinged side and filled with molten bitumen, the whole being removed from the mould after the bitumen has solidified to form a block and the sack has been closed.

Patent GB-525126-A (GB)
Title: Negative feedback amplifiers
IPC: H04B3/12
Filed: 1939-02-14
Abstract: 525,126. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 14, 1939, No. 4834. Convention date, April 15, 1938. [Class 40 (v)] A negative feedback amplifier in which the load and the feedback path are connected across diagonals of an output bridge network which is unbalanced has the impedance of the output load transformer built out to a constant resistance for a range of frequencies including a wide range extending upwards from the transmission range. The amplifier may transmit a 12-60 kilocycle range. Fig. 1 shows a threestage amplifier in which a bridge RP, Z11, R, Z21 is provided in the output feedback over a path F being connected across one diagonal and the output transformer across the other diagonal. Fig. 3 shows the output transformer T and the associated capacities 61, 62, being replaced by an equivalent network T<SP>1</SP> to form a full section of a mid-shunt terminated constant K low-pass filter. Such an arrangement will have shunt and series resonances at frequencies higher than the pass-band, which will be only slightly damped with a high impedance valve P, and are produced by the primary and secondary circuit leakage inductances and shunting capacities and by the capacity to earth of the ends of the primary winding and the inductance of the impedence Z21. The resonances will vary the gain and phase-shift for the feedback loop and reduce the singing margin and are obviated by inserting a complementary high-pass filter N in series so that the combination produces a constant resistance as described in Specification 451,633, which is resistive at frequencies well above the transmission band of the amplifier. The network N comprises a ladder type structure the product of whose series and shunt impedances and corresponding impedances in the load circuit is constant independent of frequency. The feedback path may include a tapped potentiometer 7-11 for adjusting the gain and when minimum gain is required on tap 11 the switch 44 may be opened so that the grid bias is obtained from the resistance condenser combination 45 instead of the battery 46 by operation of switch 43. The closure of switch 44 gives gain and phase conditions to avoid singing with all adjustments of the feedback potentiometer tap. A condenser GC forms a gain control potentiometer in the feedback path and a further flat gain control condenser GR may be operated by a pilot channel. A condenser 12 and inductance 13 associated with the potentiometer 7-11 adjust phase to prevent singing and the earthing of the suppressor grid of the valves V1, V2 further assists in maintaining stability.
